Beverage brewing system

ABSTRACT

A beverage cartridge system is adapted to brew a beverage through a brewer having a holder adapted to receive the cartridge system. The holder may have a deep well with one or more needles therewithin to pierce through the bottom of the cartridge system when inserted into the well. The cartridge system may include a short cup and a tall cup, where the tall cup is taller than the short cup to pack more beverage grind. The cartridge system may include a filter within an outer cup. The bottom of the filter may be deep enough to be juxtaposed to the bottom of the cup. The filter may be formed from a material that is substantially resistant to piercing by the needle within the holder such that when the outlet needle pierces through the bottom of the cup, the outlet needle raises the filter at a point of contact, and the filter substantially resists the outlet needle from piercing through the filter during a brewing process.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention is directed a beverage brewing system, and in particular,to a brewing system for making hot beverages such as coffee, tea, coco,milk, and soup.

2. Background of the Invention

There are many ways to brew coffee including drip and french pressmethods. Recently, brewing coffee through a single-serve cartridge hasbecome popular for its convenience and a variety of coffee flavors whichare offered. Single-serve cartridges are packed with pre-measured coffeegrind which can be inserted into a brewer to inject hot water into thecartridge to brew the coffee. Like any other beverage, one of theimportant criteria for a success of the beverage is its taste, andcoffee is no different. In this regard, the Coffee Brewing Center (CBC)during the 1960's, led by Dr. Earl Lockhart, has done a lot of researchin understanding the physics and science behind what constitutes a goodtasting coffee. The CBC has come up with what is called the “CoffeeBrewing Control Chart” like the one shown in FIG. 1, which provides agraphical representation of strength, extraction and brew formula in aneasy to read format.

According to the chart shown in FIG. 1, an ideal tasting coffee isobtained when there is a good combination of strength and extraction.Strength is also referred to as total dissolved solids (“TDS”), and theideal TDS level is 1.15%-1.35%. For example, TDS level of 1.00% meansthere is 1.00% of coffee concentration and the remaining 99.00% is waterin the cup. According to the chart, coffee having a TDS level below1.15% may taste weak; while coffee having a TDS level above 1.35% maytaste too strong. As a reference, coffee from a traditional coffeehouse, such as Starbucks®, may have a TDS level from about 1.20% toabout 1.35%. The TDS level may be measured using a number of differentinstruments such as hydrometers, conductivity, Brix and moisturemicrowave. In particular, a conductivity meter measures the amount ofcoffee flavoring material based on its conductivity across a coffeeinfusion.

The chart in FIG. 1 also indicates that the ideal extraction level forcoffee is 18%-22%. Extraction means amount of coffee that has dissolvedfrom the coffee grind into the coffee drink. For example, if 10 grams ofcoffee grind is brewed, and after the brewing there is 8.0 grams ofcoffee grind left, then the extraction level is 20% because 2 grams or20% of the coffee grind dissolved into coffee. Extractions below 16% mayindicate a coffee taste that is under-developed such that it may have aweak peanut-like flavor, while extractions over 22% may indicate acoffee taste that is over-extracted so it may taste bitter.

Many hot beverages, such as coffee and tea, are now provided in singleserve packs which can be inserted into a brewer to inject hot water intothe pack to brew hot beverages. For instance, US. Patent ApplicationPublication No. 2005/0051478 entitled BEVERAGE FILTER POD by Karanikoset al. (the “'0051478 Application”), which is hereby incorporated byreference, describes a beverage filter cartridge having a cup likecontainer where the interior is divided into two chambers by acup-shaped filter element: a first chamber inside the filter and asecond chamber located between the filter bottom and the containerbottom. The upper rim of the filter is joined at the upper rim of thecontainer side wall, and the filter side wall has exterior channels thatface the container side wall and lead downwardly from the peripheraljuncture to the second chamber. The filter sidewall is folded to provideexterior channels. And according to the '0051478 Application, during thebrewing cycle, the channels provide a passageway for beverage topermeate from the first chamber to the second chamber, and in so doing,improve the full saturation of the beverage grind in areas adjacent tothe container side wall.

A beverage grind, such as grinded coffee, is poured into the firstchamber, and a cover, such as an aluminum foil, is used to seal thecontainer. An input needle can pierce through the cover to inject hotwater into the first chamber to mix with the beverage grind to produce abeverage. The filter element is permeable to allow liquid beverage topass therethrough while retaining the granular beverage grind within thefilter. The beverage passes through the filter via the exterior filterchannels, and into the second chamber. An output needle can pierce thebottom of the container to allow the beverage to flow out from thesecond chamber. While the cartridge described in the '0051478Application is able to brew a sufficient cup of coffee, the cup size ofthe coffee is limited because there is a limit as to how much coffeegrind the filter can hold.

To brew a bigger cup of coffee, US. Patent Application Publication No.2010/0303964 entitled CARTRIDGE WITH FILTER GUARD by Beaulieu et al.(the “'0303964 Application”), which is hereby incorporated by reference,discloses a more elongated filter compared to the filter disclosed inthe '0051478 Application such that the space in the second chamber isminimized. With a bigger filter, more coffee grind may be inserted intothe cartridge to brew a bigger and/or stronger cup of coffee. In orderto protect the filter from the output needle piercing through the bottomof the filter, a filter guard is provided between the filter and thebottom of the cartridge so that the filter guard makes contact with theoutput needle to protect the filter. While providing a larger filter tohold more coffee grind somewhat enabled brewing a stronger tastingcoffee or a larger cup of coffee, coffee made from the cartridgegenerally described in the '0303964 Application resulted in TDS levelsof about 0.95%, which may be considered weak according the chart shownin FIG. 1. Accordingly, there still is a need to brew stronger tastingcoffee using a single-serve cartridge.

As of 2013, the market leader of single-serve cartridge platform inNorth America is Green Mountain Coffee Roasters®, which sells itssingle-serve platform under the Keurig® brand name, collectivelyreferred to as Keurig®. Keurig® offers over 200 varieties ofsingle-serve cups, also known as K-Cup®, which works with several ofKeurig’ s® brewers offered in the market today. There is estimated to beover 12 million U.S. households with Keurig® brewers in use largely dueto its convenience where a single cup of coffee can be made without muchof a cleanup. A good example of types of brewers offered by Keurig® isgenerally described in U.S. Pat. No. 7,347,138, which is incorporated byreference.

FIG. 1B is a copy of FIG. 3 of the U.S. Pat. No. 7,347,138. The brewer10 includes a brew chamber 18 comprised of a cartridge receptacle 20 anda lid 22. The receptacle 20 has a removable holder 23 configured anddimensioned to receive a beverage filter cartridge 24. The holder 23 hasa needle at the bottom to pierce through the bottom of the cartridgewhen the cartridge is pressed down into the holder. The cartridge 24includes an outer container internally subdivided by a paper filter intotwo compartments: top and bottom compartments. The top compartment isdefined by the shape of paper filter to hold coffee grind within thepaper filter. The bottom compartment is a remaining empty space withenough space so that the bottom needle does not pierce the paper filterin order to prevent the coffee grind from washing out during the brewingprocess.

The holder 23 is removable so that it may be easily cleaned. One of thecommon elements of the brewers offered by Keurig® is that they allutilize essentially the same holder 23. The holder 23 is configured suchthat when the cartridge 24 is inserted into the holder 23, the cartridge24 substantially fills the void within the holder 23 such that there islittle gap between the holder 23 and the cartridge 24. This means thatthe outer shape of the cartridge 24 is constraint by the holder 23 suchthat cartridge 24 may not be enlarged, which means that there is a limitas to how much coffee grind that can be packed within the paper filterin the cartridge 24. As discussed above, without being able to enlargethe cartridge, only other option is to enlarge the paper filter as muchas possible to hold more coffee grind to make a stronger cup of coffee,but doing so lowers the paper filter closer to the bottom needle, whichincreases the risk of the bottom needle piercing the paper filter. Asdiscussed above, the cartridge disclosed in the '0303964 Applicationutilizes a filter guard to protect the paper filter from the bottomneedle. While the cartridge disclosed in the '0303964 Application canhold more coffee grinds, there is still a limitation due to the fixedouter size of the cartridge 24. As such, there is a need to brew astronger and bigger cup of coffee utilizing the Keurig's® brewers.

INVENTION SUMMARY

This invention is directed to a cartridge system adapted to brew abeverage through a brewer having a brewing chamber adapted to receivethe cartridge system. The brewing chamber may have a deep well with oneor more needles therewithin to pierce through the bottom of thecartridge system when inserted into the well. The cartridge system mayinclude a cup having a base and a lip, a side wall between the lip andthe base defining an interior space therewithin. A filter may have adeep bowl configuration with a bottom and a side wall that tappers up toform a rim. The rim of the filter is adapted to couple adjacent to thelip of the cup, and the bottom of the filter may be deep enough to bejuxtaposed to the base of the cup. The filter may be formed from amaterial that is substantially resistant to piercing by the needlewithin the brewing chamber such that the bottom needle raises the filterat a point of contact, and the filter substantially resists the bottomneedle from piercing through the filter during a brewing process.

With the bottom of the filter juxtaposed to the base of the cup, thefilter may substantially fill the interior space of the cup to optimizethe amount of beverage grind that the cartridge system may hold. Theadditional space within the filter relative to traditional cups, such asK-cup®, the heated water injected into the cartridge may have more spaceto circulate to evenly wash or extract the flavors from the beveragegrind to provide a smoother tasting beverage.

The cartridge system may include a holder adapted to receive a firstbeverage cartridge and a second beverage cartridge. The second beveragecartridge may be longer along its longitudinal axis relative to thefirst beverage cartridge. The holder may have a side wall between a lipand a basin defining a well. The holder may also have a first needle anda second needle within the well, where the first needle is positionbetween the lip and the second needle. The first needle may be adaptedto pierce through the first beverage cartridge, and the second needlemay be adapted to pierce through the second beverage cartridge.

A portion of the side wall of the second beverage cartridge may have acavity along its longitudinal axis adapted to receive the first needlesuch that the first needle does not pierce through the cup. The secondneedle, however, may pierce through the bottom of the second beveragecartridge. The interior space of the second beverage cartridge may beabout 20% to about 40% larger than the first beverage cartridge whereits outer dimensions may be substantially similar to K-cup®. The extraspace within the second beverage cartridge allows for brewing a biggerand/or stronger cup of beverage.

The cartridge system may also have a filter that divides the interiorspace of the cup between a first chamber and a second chamber. The firstchamber may be substantially defined by the interior space of thefilter, and the second chamber may be generally defined by the spacebetween the bottom of the filter and the base of the cup. The firstchamber may be packed with a first beverage grind such as coffee grind.The second chamber may be packed with a second beverage grind such aspowder cream that substantially dissolve instantly as the heatedbeverage permeate out of the filter and into the second chamber so thatthe combination of the beverage and the dissolved powder cream does notclog the needle.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 2 shows an expanded view of a cartridge system 100 adapted to brewa beverage. The cartridge system may include a cup 102 adapted to housea filter 104. The filter 104 may be adapted to hold beverage grind, suchas grind coffee or tea, therewithin. A ring 106 may be coupled to a rim108 of the filter 104, and as the filter is fitted inside the cup 102,the ring 106 may releasably engage with an inner ledge 110 formed withinthe cup 102. With beverage grind placed inside the filter 104, a cover112 may enclose the cup 102 by sealing around the outer circumference114 of the cover 112 to a rim 115 of the cup 102.

FIG. 2 also shows a holder 116 having a well 117 adapted to receive thecartridge system 100. The well 117 may be defined by a lip 118 withcavities 120 adapted to receive a pair of ears 122 from the cup 102. Thelip 118 may also have a pointer mark 124 to define a first orientation123 of the holder 116, and a second orientation 125, which may be on theopposite end of the lip 118. The cup 102 may have a ledge 126 with anopening 128 with its shape being substantially similar to the pointermark 124 on the lip 118. As such, the cup 102 may be fully inserted intothe holder 116 when the pair of ears 122 generally line up with thecavities 120, and the ledge 126 with the opening 128 on the cup toindicate to the user to point the ledge 126 towards the firstorientation 123 of the holder 116 such that when the cup 102 is fullinserted into the holder 116, the pointer mark 124 on the lip 118 may beseen through the opening 128. The cup 102 may have a base 129 sized tofit within the well 117 of the holder.

FIG. 3A shows a perspective interior view of the well 117 of the holder116. Within the well, the holder 116 may have a first needle 130 and asecond needle 132. The first needle 130 may be located towards the firstorientation 123 of the holder 116. The holder 116 may have a stopperledge 141 to support the first needle 130 such that the first needle 130may be adjacent to the pointer mark 124 on the lip 118. The secondneedle 132 may be located towards the second orientation 125 of theholder 116, and the second needle 132 may protrude from the basin 143 ofthe holder. The well 117 may have one or more rib lines 134 along thelongitudinal axis of the holder 116. The well 117 may have inner surfaceareas 119 segmented by the rib lines 134. The needle 130 may be adaptedto pierce through the base 129 of the cup 102. The lip 118 may have tabs136 adapted to engage with a brewer (not shown), which may inject hotwater into the cartridge system 100.

FIG. 3B shows a bottom perspective view of the holder 116. The holdermay have a bottom end 131 on the opposite side of the lip 118. Theholder 116 may have a first funnel 133 coupled to the first needle 130such that liquid may pass through the first needle 130 and exit througha first outlet 137. The holder 116 may have a second funnel 135 coupledto the second needle 132 such that liquid may pass through the secondneedle 132 and exit through a second outlet 139.

FIG. 4A shows a bottom perspective view of the cup 102. The cup 102 mayhave a base 129 defining a side wall 140 extending between the rim 115and the base 129. A portion of the side wall 140 near the base 129 mayhave one or more corner 142 defining a target area 144 along the base129 between the two corners 142. In general, the corners 142 may bemirror image of each other, and each of the corner 142 may have a bend146 defining perpendicular walls 148. The target area 144 may bejuxtaposed to the ledge 126. The base 129 may have one or more innerribs 150, and the side wall 140 may have one or more inner ribs 152along the longitudinal axis of the cup 140. As the cup 102 is insertedinto the well 117 of the holder, the inner ribs 152 may accommodate therib lines 134 within the well 117 of the holder 116; and the side wall140 of the cup 102 may be adjacent to the inner surface area 119 of thewell 117. The rim 115 may have a line of weakness 121so that the ledge126 may be separated along the line of weakness 121 from the rim 115 byapplying pressure on the ledge 126.

FIG. 4B shows a perspective view of the cup 102 where a basin 154 may beformed between the two corners 142. Channels 156 may be formed betweentwo adjacent ribs 152 such that wider gaps may be formed between thechannels 156 and the sidewall of the filter 104. This may allow thebeverage permeating out of the filter 104 to flow down into the basin154 with less resistance. Base channels 158 may also be formed on thebase 129 between the inner ribs 150 to guide liquid or beverage on thebase 129 toward the basin 154.

FIG. 5A shows a perspective view of the filter 104 with a side wall 161that is folded such that the side wall 161 may be corrugated to formchannels 160 between adjacent peaks 162 along the longitudinal axis ofthe filter 104. The ring 106 may be coupled to the rim 108 of the filter104. The ring 106 may have an inner side 164 and an outer side 166. Therim 108 of the filter 104 may be coupled to the inner side 164 or theouter side 166. The rim 108 of the filter 104 may be coupled to the ring106 through a variety of methods known to one skilled in the art, suchas using adhesive or ultrasonic welding. It is also within the scope ofthe invention to have the rim 108 of the filter 104 to be sealeddirectly onto the inner wall of the cup near the inner ledge 110. Thefilter 104 may have a base 168 with an indentation 170 along the base168 to accommodate the corners 142 of the cup 102 such that the filter104 substantially fill the space within the cup 102.

FIG. 5B shows a top perspective view of the cup filter 104 with moredetail view of the channels 160 and peaks 162. The indentation 170 alongthe portion of the base 162 may form a step 172, which may be supportedby the corners 142 such that when the second needle 132 pierces throughthe basin 154 of the cup 102, the second needle does not pierce throughthe step 172 of the filter 104 thus eliminating the need for a filterguard as the one described in the '0303964 Application.

FIG. 6 shows cross-sectional views of the cartridge system 100 and theholder 116. The cartridge system 100 may be assembled by inserting thefilter 104 into the cup such that the ring 106 may be press fitted intothe inner ledge 110 to substantially minimize the hot water injectedinto the beverage grind in the filter 104 from passing through the gapbetween the ring 106 and the inner ledge 110. The step 172 of the filter104 may rest on the corners 142 of the cup, and the base 162 of thefilter 104 may be adjacent to the base 129 of the cup 104 such that thefilter 104 substantially contours the inner surface of the cup 102. Theinner ribs 150 on the base 129 may provide a gap between the base 162 ofthe filter 104 and the base 129 of the cup. Once the beverage grind hasbeen poured into the filter 104, the outer circumference 114 of thecover 112 may be sealed over the rim 115 of the cup 102. The cover 112may be sealed onto the cup 102 through a variety of methods known to oneskilled in the art, such as adhesive and pressure sensitive adhesive sothat the cover may be peeled off after use if desired. For instance,after the cartridge system 100 has been used to make a beverage, theledge 126 may be broken off from the rim 115 along the line of weakness121, and as the ledge 126 is lifted, the cover 112 may also peel offfrom the rim 115 of the cup. With the cover 112 removed, the filter 104with the used beverage grind in the filter may be removed from the cup102 by pulling on the ring 106; thus separating the cup 102 fromcartridge system 100. The cup 102 may be made from recyclable materialso that it can be recycled if desired.

To insert the cup 102 into the holder 116, the pair of ears 122 may beline up with the cavities 120 along the lip 118. The first needle 130may be coupled to the stopper ledge 141 within the well 117. The firstneedle 130 may be coupled to the first tunnel 133, and once the firstneedle 130 pierce through the target area 144 of the cup 102, beveragemay pass through the first needle 130 and exit through the first outlet137. The second needle 132 may protrude from the basin 143 of the holder116, and the second needle 132 may be coupled to the second funnel 135,and beverage may exit through a second outlet 139.

FIG. 7 shows a cross-sectional view of the cartridge system 100 insertedinto the holder 116. The cartridge system 100 may be inserted into theholder 116 such that the opening 128 may align with the pointer mark 124on the lip 118 such that the ledge 126 may point towards the firstorientation 123 relative to the holder 116. As the cartridge system 100is inserted in the first orientation relative the holder 116, the firstneedle 130 may pierce through the target area 144 of the cup 102. Thestopper ledge 141 of the holder 116 may abut against the target area 144of the cup 102 to support the cup 102 within the holder 116. Note thatthe second needle 132 does not pierce the cartridge system 100.

A brewer system 180 may be provided to brew a beverage. The brewersystem 180 may include an injection needle 182 adapted to pierce throughthe cover 112. The brewer system 180 may include a pump 184 to deliverheated liquid, such as water, though the injection needle 182, and intothe cup 102. The solid direction arrows 186 may generally illustrateflow of hot liquid injected into the cup 102 to wash the beverage grindwithin the filter 104, and pass through the filter 104. The beverage mayutilize the channels 160 to drop down into the base channels 158 of thecup 102, and exit through the first needle 130 to pass through the firstchannel 133 and exit through the first outlet 137.

FIG. 8A shows a graph generally representing distribution of grind sizesof a coffee formulation 190 provide in a single serve cartridge soldunder the trade name of K-Cup® by Green Mountain Coffee Roasters, Inc.The coffee grind sizes provided in the K-Cup® generally vary from about0.35 mm to about 0.60 mm with a median grind size 192 being about 0.50mm. While coffee brewed from K-Cup® provide adequate coffee strength,the brew time or flow rate of hot water through the K-Cup® is relativelyshort compared to a traditional drip coffee method. In addition, thenarrow range of the coffee grind sizes may result in uneven saturationof the coffee grind such that an upper portion of the coffee grind mayhave greater extraction percentage compared to the lower portion of thecoffee grind. This may result in low extraction of coffee from thecoffee grind such that the TDS level may be low.

FIG. 8B shows a graph generally representing distribution of grind sizesof a coffee formulation 200 provide in a single serve cartridge inaccordance with this invention including a first portion 202 and asecond portion 204. The first portion 202 of the coffee grinds may berepresented by a graph 206 where the grind sizes varies from about 0.18mm to about 0.40 mm, and a median grind size 208 of about 0.32 mm. Thesecond portion 204 of the coffee grinds may be represented by a graph210 where the grind sizes varies from about 0.38 mm to about 0.95 mm,and a median grind size 212 of about 0.75 mm. It is within the scope ofthis invention to have broader and/or narrow grind sizes for the firstpotion 202 and the second portion 204 such that there may or may not bean overlap between the graphs 206 and 210. The weight ratio between thefirst and second portions may be from about 1:1 to about 3:1, andpreferably about 2:1. The coffee formulation 200 may be provided in avariety of single cartridge system including K-Cup® and the cartridgesystem 100 described above.

The coffee formulation 200 may be formulated by grinding the firstportion 202 within the grind sizes mentioned above, and grinding thesecond portion 204 within the grind sizes mentioned above. Thereafter,the proper weight ratio between the first and second portions, asdiscussed above, may be mixed together to formulate the coffee grind200. In general, the median grind size 208 of the first portion 202 maybe smaller than the median grind size 192, and the median grind size 212of the second portion 204 may be larger than the median grind size 192.With a combination of distinct smaller and larger coffee grinds of thecoffee formulation 200 compared to the coffee formulation 190, the hotliquid may more evenly saturate the coffee formulation 200 to extractmore coffee from the combination of the coffee grinds, which may resultin a stronger coffee. Moreover, the first portion 202 with smaller grindsizes compared to the coffee formulation 190 may slow down the flow ofhot liquid through the coffee formulation 200, thus allowing more timefor the hot liquid to extract the coffee beverage from the coffeeformulation 200.

Table 1 below shows the test results of coffee brewed from coffeeformulations 190 and 200. In preparation for the test, Starbucks'® CaffeVerona Dark roast K-Cups® were purchased, which is generally made inaccordance to the cartridge described in the '0303964 PatentApplication. The amount of coffee grind in each of the K-Cup® varied. Toestablish a common base line, aluminum foil cover was opened, and thecoffee grinds were poured out and measured using a digital weight meter.An average weight was 12.3 grams of coffee grinds. Using this as a baseline, 12.3 grams of same coffee grinds were poured back into emptyK-Cup®, and resealed using a new aluminum foil with adhesive layer onone side. The aluminum cover was wrapped over the rim of the cup. FiveK-Cups® were made with 12.3 grams of the same coffee grind in eachK-Cup®, and they were labeled 1A, 2A, 3A, 4A, and 5A.

From a Starbucks® store, a bag of Dark Caffe Verona® whole bean coffeewas purchased. The whole beans were grinded using an Encore CoffeeGrinder manufactured by Baratza®. This grinder has many settings togrind the coffee beans in different sizes. Setting the grinder to number8 grinded the coffee to produce the grind sizes generally described inthe first portion 202, and setting the grinder to number 22 grinded thecoffee to produce the grind sizes generally described in the secondportion 204. The assumption here is that using the same type of coffeebeans “Dark Caffe Verona” from the same company, Starbucks®, for testingwould minimize the variances in the testing.

After the first and second portions 202 and 204 were grinded, the coffeeformulation 200 were made by mixing about 2:1 weight ratio of first andsecond portions, respectively. Using the same empty Starbucks' K-Cups®,five K-Cups® were refilled with 12.3 grams of the coffee formulation200, and they were labeled 1B, 2B, 3B, 4B, and 5B. Then in alternatingorder, as noted below in Table 1, each K-Cups® were inserted into aKeurig® B70 brewer to make coffee. During each brewing cycle, the sizeof the coffee in (oz), temperature of the coffee in the cup, and thebrew times were measured, as noted below.

After the 10 cups coffee were made, the coffee were allowed to cool toroom temperature, then the TDS level were measured using a digitalconductivity meter from HM Digital, Inc., model no. COM-100. As notedabove, B70 consistently brewed same amount of coffee or about 7 oz.However, the average brew time for the coffee formulation 190 was about34.2 seconds, while the average brew time for the coffee formulation 200was about 41.4, which is about 7.2 seconds longer than the coffeeformulation 190. The longer brew time may have contributed brewing astronger coffee because the average TDS level for the coffee formulation200 is about 1.06% compared to the average TDS level for the coffeeformulation 190, which is about 0.98%. This means that the coffeeformulation 200 brews about 8% stronger coffee compared to the coffeeformulation 190 using same amount of coffee.

FIG. 9 shows an expanded view of a cartridge system 300 adapted to brewa beverage. The cartridge system 300 may include an elongated cup 302adapted to house an elongated filter 304. The elongated filter 304 maybe adapted to hold beverage grind, such as grinded coffee or tea,therewithin. A ring 106 may be coupled to a rim 308 of the elongatedfilter 304, and as the filter is fitted inside the elongated cup 302,the ring 106 may releasably engage with an inner ledge 310 formed withinthe elongated cup 302. With beverage grind placed inside the elongatedfilter 304, the cover 112 may enclose the elongated cup 302 by sealingan outer circumference 114 of the cover 112 around the rim 315 of theelongated cup 302. The holder 116 may be adapted to receive thecartridge system 300 within the well 117 such that the second needle132may pierce a target area 312 on the base 314. The elongated cup 302 mayhave a side wall 316 between the rim 315 and the base 314. The side wall316 may have a cavity 318 along a portion of the elongated cup 302 alongits elongated axis below a ledge 326. The cavity 318 may be adapted toreceive the first needle 130 such that the first needle 130 may notpierce the elongated cup 302 as discussed in more detail below.

FIG. 10 shows a bottom perspective view of the elongated cup 302 thatmay be similar to the cup 102 described above, except that the side wall316 may have the cavity 318 extending partially along the longitudinalaxis of the elongated cup 302 underneath the ledge 326, and the base 314may have a recess 319 adapted to receive the first needle 130 as the cup302 is inserted into the holder 116. The base 314 may have a target area320 on the opposite side of the recess 319. The distance between the rim315 and the base 314 of the elongated cup 302 may be greater than thedistance between the rim 115 and the base 129 of the cup 102.

FIG. 11 shows a cross-sectional view of the cartridge system 300inserted into the holder 116. The cartridge system 300 may be insertedinto the holder 116 such that an opening 328 within the ledge 326 mayalign with the pointer mark 124 on the lip 118 such that the cartridgesystem 300 may be inserted so that the ledge 326 points towards thefirst orientation 123 relative to the holder 116. As the cartridgesystem 300 is inserted towards the first orientation relative the holder116, the cavity 318 of the elongated cup 302 may receive the firstneedle 130 without pierce the elongated cup 302. The second needle 132,however, may pierce the target area 320 of the elongated cup 302.

A brewer system 180 may be provided to inject hot water through theinjection needle 182 adapted to pierce through the cover 112. The soliddirection arrows 330 may generally illustrate flow of hot liquidinjected into the elongated cup 302 to wash the beverage grind withinthe filter 304, and pass through the filter 304. The beverage may dropdown into the base 314 of the cup 302, and exit through the secondneedle 132 to pass through the second channel 135 and exit through thesecond outlet 139. The elongated filter 304 may hold more beverage grindthan the filter 104 so that a bigger cup of beverage may be brewed.Moreover, the elongated filter 304 may hold the coffee grind in anelongated form such that it may take longer time for hot water from theinjection needle 182 to flow through the coffee grind and reach thesecond needle 132. The longer contact time between the hot water and thecoffee grind may allow for greater extraction of coffee beverage fromthe coffee grind to brew stronger coffee. Note, it is within the scopeof the invention to configure the elongated cup 304 to have both of thefirst and second needles 130 and 132 pierce the elongated cup 304.

FIG. 12A shows a cross-sectional view of a cartridge system 400. Thecartridge system 400 may be similar to the cartridge system 100, asdiscussed above, except that a filter 404 within the cup 102 may beshorter than the filter 104 such that the cup 102 may be dividedgenerally into a first chamber 406 and a second chamber 408. The firstchamber 406 may be the space within the filter 404 adapted to hold afirst beverage grind 410. The second chamber 408 may be the spacebetween a bottom 409 of the filter 404 and the basin 154 of the cup 102.The second chamber 408 may hold a second beverage grind 412. Forexample, the first beverage grind 410 may be coffee grind, and thesecond beverage grind 412 may be powder creamer and/or sweetener.

Incorporating creamer in the second chamber 408 allows creamer to beadded to the coffee beverage in one-step process. As hot water injectedthrough the injection needle 182 extract coffee from the coffee grind410 within the filter 404, the hot coffee beverage passes through thefilter 404 and enters the second chamber 408, and dissolves the powdercreamer 412. The combination of creamy coffee may then exits through thefirst needle 130. One of the desirable characteristics of powder creameris to dissolve quickly and thoroughly so that the powder creamer doesnot clog up the first needle 130. In this regard, powder creamers usedin instant coffee may be utilized. In particular, powder creamer made inaccordance with Korean patent application publication number1020120042406 with publication date of Mar. 5, 2012 entitled “PRODUCINGMETHOD OF COFFEE CREAMER POWDER HAVING IMPROVED MILK FLAVOR,” (the“'42406 Application”) may be used utilized, which is hereby incorporatedby reference.

Note, it is within the scope of this invention to incorporate a secondbeverage grind 412 into the second camber in the K-Cup®, which is thespace between the bottom of the filter and the bottom of the cup. With afinite space in the K-Cup®, the weight ratio between the coffee grind inthe filter and the creamer may vary. For instance, with the creamerdescribed in the '42406 Application, the coffee grind to creamer weightratio may be from about 2:1 to about 2:3, and in particular about 1:1.For instance, while taste can be subjective, a good milky coffee tastewas obtain when 6.0 oz cup was brewed using about 10.0 grams of coffeegrind in the first chamber, and about 9.0 grams of creamer in the secondchamber using a K-Cup®. While it was possible to add more coffee grindand creamer into the first and second chambers, respectively, doing somay in some instances cause the coffee grind and creamer to be tooclosely packed together within the K-Cup®. This increased the resistanceto flow of hot water through the coffee grind such that hot water mayleak out through the gap between the injection needle 182 and the cover112. Moreover, adding more creamer to the second chamber, in someinstance, caused the creamer to not dissolve thoroughly such that clumpsof creamer were left in the bottom of the cup. As such, in someinstances, adding more creamer had the opposite effect in that lessmilky flavor were detected in the coffee because not all of the powdercream dissolved into the coffee.

FIG. 12B shows a cross-sectional view of a cartridge system 500. Thecartridge system 500 may be similar to the cartridge system 300, asdiscussed above, except that the filter 104 may be incorporated into thecup 302 to generally divide the elongated cup 302 into a first chamber506 and a second chamber 508. The first chamber 506 may be the spacewithin the filter 104 to hold more beverage grind than the cartridgesystem 400, and hold more creamer in the second chamber 508. This allowsthe cartridge system 500 to brew a bigger cup of coffee with creamer inone-step process compared to the cartridge system 400. In addition toincorporating creamer and sweetener in the second chamber 508, othertaste flavoring may be added to enhance the taste the beverage.Moreover, scent enhancing materials may be added in the second chamberto enhance the aroma scent of coffee to intensify the aroma smell fromthe cup of coffee.

FIG. 13A shows a perspective view of a cartridge system 600 similar tothe cartridge system 400, as discussed above, with the followingdifferences. The cartridge system 600 includes a filter 602 within a cup604. The rim 606 of the filter 602 may be sealed around the inner edge608 located adjacent to the rim 610 of the cup 604. The cup 604 may nothave corners 142 along the bottom, as described in reference to the cup102, to maximize the space of the second chamber, as discussed in moredetail below. The cup 604 may be sized to have similar dimensions asK-Cup® such that the outer diameter D1 adjacent to the rim 610 of thecup may be from about 40.0 mm to about 47.0 mm, and in particular about45.5 mm. The bottom outer diameter D2 may be from about 34.0 mm to about38.0 mm, and in particular about 36.5 mm.

FIG. 13B shows a cross-section view of the cartridge system 600 alongthe line 13-13 of FIG. 13A. The filter 606 within the cup 604 may beshorter than the filter 104 such that the cup 604 may be dividedgenerally into a first chamber 612 and a second chamber 614. The secondchamber 614 may be filled with the second beverage grind 412 such aspowder creamer and/or sweetener to a level H3 from a basin 616 of thecup 604. The filter 602 may be sized to substantially fill the remainingspace within the cup 604 such that a distance between the rim 610 of thecup and a bottom 618 of the filter 602 may be about H2. The filter 602may be sealed to the inner edge 608 of the cup after the second beveragegrind 412 is filled within the second chamber 614 such that the bottom618 of filter may be substantially horizontal relative to the basin 616.The height of the cup 604 between a bottom 620 and the rim 610 of thecup 604 is H1. The distance H1 may be from about 43.0 mm to about 46.0mm, and in particular about 44.5 mm. In situations where the bottom 618of the filter 602 substantially makes contact with the second beveragegrind 412, the H1 may be about the sum of H2 and H3.

In applications where the system 600 is used for brewing creamy coffeein one-step, the distance H3 may be about 30% to about 60% relative tothe distance H1; and in particular, the distance H3 may be about 40% toabout 50% relative to the distance H1. The distance H3 may varydepending on the desired creamy flavor of the coffee, where adding morecream, or increasing H3, relative to the coffee grind may add morecreamy flavor to the coffee, and vice versa. The distance H2 may beabout 40% to about 70% relative to the distance H1; and in particular,the distance H2 may be about 50% to about 60% relative to the distanceH1. The cup 604 may also have the volume ratio between the first andsecond chambers 612 and 614 from about 3:7 to about 6:4, and inparticular from about 2:3 to about 1:1.

The distance H1 may be greater than the sum of H2 and H3 such that theremay be a gap between the bottom 618 of the filter 602 and the secondarybeverage grind 412. Providing a gap or space between the filter 602 andthe secondary beverage grind 412 may improve the dissolvability ofpowder cream within the second chamber 614. This may be due to providingextra space within the second chamber 614, which may improve thedissolvability of the power cream.

FIG. 13C shows a cross-section view of a cartridge system 600 with thefilter 606 within the cup 604 holding coffee grind 607, and the secondchamber 614 may have a pouch 615 filled with the second beverage grind412 such as powder creamer and/or sweetener. The pouch 615 may be a meshfilter to contain the powder creamer therein and allow the powdercreamer to permeate when dissolved with hot water. The pouch 615 may besized to contain the second beverage grind 412 to substantially preventthe grind 412 from making contact with the filter 606 thereby providinga space 618 between the filter 606 and pouch 615. Providing a gap orspace between the filter 606 and the grind 412 may improve thedissolvability of the powder grind 412. Moreover, the pouch 615 may bemade of a mesh filter material that may substantially resist beingpunctured by the first needle 130 at the bottom of the cup holder 116such that the pouch 615 conforms around the needle 130, as shown in FIG.13C. This may substantially prevent the dry powder cream from passingthrough the needle 130 and dropping into the cup before the powder creamdissolve into liquid form. However, it is within the scope of theinvention to have the needle 130 pierce through the pouch 615.

The amount of powder cream within the second chamber 614 and/or pouch615 may vary depending on the desired creamy and/or sweetness flavor. Asa way of background, Keurig® brewers for K-Cups® generally takes about30 to about 35 seconds for hot water to pass through the K-Cup® forabout an 8 oz cup of beverage. The powder cream may be formulated andthe amount of powder cream within the second chamber 614 and/or pouch615 may be such that the powder cream substantially dissolves less thanabout 25 seconds for an 8 oz cup of beverage so that the bottom needlemay be rinsed or purged with the remaining 5 to 10 seconds with hotbeverage. This allows the bottom needle to be substantially kept cleanso that in the next brew cycle, the beverage may have minimal powdercreamy residue.

FIG. 14 shows the bottom 620 of the cup 604 having a circular line ofweakness 622. The cup 604 may be made from a recyclable material, whichmay be harder than the non-recyclable material. With the hardermaterial, it may take more downward force to have the bottom needlepierce through the bottom 620 of the cup 604 near the target area 624,which may dull the tip of the needle. The line of weakness 622 maycircle the target area 624 to minimize the force it takes to piercethrough the target area 624. Alternatively, a hole may be formed on thetarget area and the hole may be sealed with an aluminum foil so that thebottom needle may pierce through the aluminum foil with nominal force.

FIG. 15A shows a perspective view of a cartridge system 700 including acup 702 with a side wall 704 between a rim 706 and a bottom 708. Thesystem 700 may include a lid 710 to cover the rim 706 to hold thebeverage medium within the cup 702. The side wall 704 may be integratedwith filter elements 712 between ribs 714. The ribs 714 maysubstantially extend between the rim 706 and the bottom 708. The bottom708 may be a solid base or integrated with filter element as well. Thecup 702 may have a recess 716 formed along the bottom 708 and the sidewall 702 adapted to receive the bottom needle when the cup 702 isinserted into the cup holder 116 such that the bottom needle does notpierce the cup 702. The lid 710 may have a ledge 719 to indicate theproper orientation of the cartridge system 700 so that the cartridgesystem 700 may be inserted in the proper orientation within the holder116 such that the bottom needle is within the recess 716 of the cup 702.

FIG. 15B shows a side view of the cartridge system 700 with the filterelements 712 integrated between the ribs 714. The cup 702 may be sizedto substantially fill the well 117 of the cup holder 116 to maximize theamount of coffee grind the cup 702 can hold. The ribs 714, rim 706, andthe bottom 708 may be made from a plastic material, and the filter maybe made from a mesh with sufficient pores to allow the beverage to passtherethrough while keeping the beverage medium therein.

FIG. 15C shows a cross-sectional view of the cartridge system 700 withina cup holder 718. The cup holder 718 may have a first outlet needle 720and a second outlet needle 722. The first outlet needle 720 may belocated between a lip 724 of the holder 718 and the second outlet needle722 along a longitudinal axis 726 of the holder 718. The lip 724 mayalso have an pointer mark 728 to orient the cartridge system 700 in thedirection where the ledge 719 faces the pointer mark 728 such that whenthe cartridge system 700 is inserted into the cup holder 718, the firstoutlet needle 720 is within the recess 716 of the cup 702. With thefilter element 712 integrated within the side wall 704, the space withinthe cup 702 may be enlarged to hold more of the beverage medium 730.

FIG. 16 shows a cross-sectional view of the cartridge system 800 withinthe cup holder 718. The cartridge system 800 includes a cup 802 with aside wall 804 between a rim 806 and a bottom 808. The cup 802 may belonger relative to the cup 702 such that the bottom 808 of the cup maybe adjacent to the base 732 of the cup holder 718. The side wall 804 maybe integrated with filter elements 812 between ribs 814. The cup 802 maybe configured to not interfere with the first and second outlet needles720 and 722. With the cup 802 being taller than the cup 702, the cup 802may hold more beverage medium such as coffee grind. In particular, themedian coffee grind size in the cartridge system 800 may be larger thanthe median coffee grind size used in the cup 702 or in K-Cup® by about10% to about 30% to minimize the resistance to flow of hot water flowingfrom top to bottom.

FIG. 17 shows a perspective cross-sectional view of a cartridge system900. The cartridge system 900 includes a cup 902 adapted to receive afilter 904. The filter 904 may have a rim 906 sized to press fit into aninner ledge 910 of the cup 902. The filter 904 may have a side wall 912between the rim 906 and a bottom 914. The filter 904 may be integratedwith filter elements 916 between ribs 918. The filter 904 may have arecess 920 formed along the bottom 914 and the side wall 912 adapted toreceive the bottom needle when the cup 902 is inserted into the cupholder 718 such that the bottom needle does not pierce the cup 902.

FIG. 18A shows a perspective cross-sectional view of a cartridge system1000. The cartridge system 1000 includes a cup 1002 adapted to receive afilter 1004. The cartridge system 1000 may be taller than the cartridgesystem 900 such that the cup 1002 and filter 1004 are longer than thecup 902 and filter 904 adapted to hold more beverage medium such ascoffee grind. The filter 1004 may be configured to not interfere withthe second outlet needle 722.

FIG. 18B shows an outer configuration of the cup 1002 adapted to fitinside the cup holder 718. The cup may have a base 1003 and a lip 1005,and a side wall 1009 between the lip and the base. The side wall 1009may have a cavity 1011 along the longitudinal axis of the cup 1002forming a substantial recess 1013 on the base 1003. The size of therecess 1013 may be substantially greater than the size of the cavities1015 formed between two adjacent ribs 1017. The cavity 1011 may beadapted to receive the first outlet needle 720 such that the needle 720does not pierce the cup. However, it is within the scope of theinvention to have both the first and second outlet needles pierce thecup. Conversely, it is within the scope of the invention to not have thefirst and second outlet needles pierce the cup such as when a mesh cupis used.

FIGS. 19A-19C show a various perspective views of the cup holder 718having the first and second outlet needles. The cup holder 718 may havea main body 740 and a funnel 742 releasably coupled to the main body740. FIG. 19D shows a perspective view of the main body 740 without thefunnel. The outer shape of the cup holder 718 may be substantiallysimilar to the cup holder 23 provided with Keurig® brewers, as discussedabove in reference to FIG. 1B, such that the cup holders 718 and 23 maybe interchangeable without interfering with the closing and openingactuation of the lid 22 and receptacle 20 of the brewer 10. This allowssome 12 million U.S. households with a Keurig's® brewer to be compatiblewith K-Cups® and cartridge systems 100, 300, 400, 500, 600, 700, 800,900, and 1000, as discussed above. This would allow the Keurig® brewersto brew not only small cup of coffee but a larger and stronger cup ofcoffee with the taller cartridge systems 300, 800, and 1000. Inaddition, coffee mixed with cream and/or sweetener may be brewed inone-step with the cartridge systems 400, 500, and 600. Note that it iswithin the scope of the invention to interchange the various filtersdisclosed in this application to have coffee and creamer integrated intoone cartridge system.

The cartridge 804 may have a ledge 818 to orient thecartridge 804 so that the cartridge 804 may be inserted into the cupholder 802 with the ledge oriented towards the pointer mark 820 on thecup holder 802.

When the cartridge 804 is inserted into the cup holder 802, the needle806 may pierce a target area 822 on the base 814, and the indentationcorners 812 may receive the tabs 808 to allow the needle 806 to fullypierce through the target area 822. With the brewing chamber system 800,the traditional K-cups® without the corners 812 may not fully fit insidethe cup holder 802 due to the tabs 808 substantially blocking the baseor bottom of the traditional K-cups® from being fully inserted. With thebrewer chamber system 802, the cup holder 802 and the cartridge 804 mayfunction as a lock and key system such that unauthorized cartridges,without the corners 812, may not work with the cup holder 802. Note thatit is within the scope of the invention to utilize a variety of otherlock and key features such that only authorized cartridges may be fullyinserted into a cup holder such as the cup holder 802. For instance, itis within the scope of the invention to have one tab 808, and the tab808 may be located anywhere in the bottom of the cup holder. Inaddition, other protrusion element may be provided within the well 810to function as a lock, and the cartridge 804 may have correspondingindentation adapted to receive the protrusion so that the cartridge maybe fully inserted into the well 810 to allow the needle 806 to piercethe target area 822.

With the K-cup® patents, U.S. Pat. Nos. 5,840,189 and 5,325,765, nowexpired, many unauthorized alternative cartridge may be introduced towork with Keurig® brewers. In order to prevent the unauthorized genericcartridges from working with the Keurig® brewers, the cup holdersprovided with the Keurig® brewers already in the market place, such asthe holder 23, may be replaced with a cup holder specially configured towork with an authorized cartridge such as the cup holder 802 and thecartridge 804.

FIG. 21A shows an expanded perspective view of a cartridge system 900including a rib cage 902 with a plurality of ribs 904 extending from arim 906 and converging at a bottom 908. The rim 906 may have a ledge 910to orient the cartridge system 900 in the proper direction wheninserting the cartridge system 900 into the cup holder 718. The rib cage902 may have a shield 912 between two adjacent ribs 904 near the ledge910. The rib cage 902 may be adapted to receive a filter mesh 914 havinga rim 916. The filter mesh 914 may be flexible and inserted into the ribcage 902, and the rim 916 of the filter 914 may be coupled or sealed tothe rim 906 of the rib cage 902. Once the filter mesh 914 is insertedinto the rib cage 904, the filter mesh 914 may conform to the shape ofthe rib cage 904 such that the filter mesh 914 may form a recess 918 dueto the shield 912. The recess area 918 may be adapted to receive thebottom needle when the cartridge system 900 is inserted into the cupholder 718 such that the bottom needle does not pierce the filter mesh914. The cartridge system 900 may include a lid 920 adapted to seal therim 906 of the rib cage 904. The cartridge system 900 filled with coffeegrind within the filter 914 may be placed inside a pouch and sealed tokeep the coffee grind fresh.

FIG. 21B shows a perspective view of an assembled cartridge system 900with the filter mesh 914 within the rib cage 902, and the lid 920enclosing the rim 906 of the rib cage 902 and/or rim 916 of the filter914. The filter mesh 914 conforms to the shape of the shield 912 to formthe recess area 918. The ribs 904 may join at the bottom 908 such thatthe filter mesh 914 at the bottom may be porous to allow beverage topermeate.

FIG. 22A shows an expanded perspective view of a cartridge system 1000that is similar to the cartridge system 900 described above with thefollowing differences. The cartridge system 1000 includes a rib cage1002 with a plurality of ribs 1004 adapted to receive the filter mesh1008. The ribs 1004 may converge at a bottom 1006 forming a nipple likeconfiguration. The rib cage 1002 and the filter mesh 1008 may be longerthan the rib cage 902 and the filter 914 so that the filter mesh 1008may hold more beverage grind. The cartridge system 1000 may have a lid1010 to seal the rim 1015 of the rib cage 902.

FIG. 22B shows a cross-sectional view of the cartridge system 1000within the cup holder 718. The cartridge system 1000 may be configuredsuch that the first and second outlet needles 720 and 722 may not piercethe filter mesh 1008. Hot water injected through the top needle 182 maypass through the beverage grind and pass through the filter mesh 1008 asindicated by direction arrows 1012 and drip down into a cup. The bottom1006 having a nipple configuration may allow the beverage to flow downsmoothly. It is within the scope of this invention for the cartridgesystem 1000 to be used as a reusable refill cup where the lid 1010 maybe pivotably coupled to the rim 1015 at a pivot axis 1011 to allow thelid to open and close. A user may open the lid 1010, fill the cup withits own coffee grind, and close the lid to substantially seal the coffeegrind within the cup. The lid 1010 may have a deep cavity 1013 adaptedto receive the needle 182 without piercing the lid. The deep cavity 1013may be porous to allow the heated water from the needle 182 to passtherethrough.

FIG. 23 shows a perspective view of a cartridge system 1100 that issimilar to the cartridge system 1000 described above except that a ribcage 1102 may have a skirt 1104 extending down from a rim 1106, and ribs1108 extending down from the skirt 1104. The skirt 1104 maysubstantially prevent beverage from permeating through the top portionof the filter mesh 1008 such that the beverage permeates through theopen filter mesh areas 1110. This may allow the beverage grind withinthe filter mesh 1008 to be more evenly saturated or washed with hotwater. Without the skirt 1104, the beverage grind near the bottomportion of the filter mesh 1008 may increase the resistance to flow ofliquid such that the beverage grind near the bottom portion may not getsufficient saturation from the hot water injected through the top needle182. In addition, to allow more even saturation along the longitudinalaxis of the filter mesh 1008, the median coffee grind size in thecartridge system 1100 may be larger than the median coffee grind sizeused in the cup 702 or in K-cup® by about 10% to about 30% to minimizethe resistance to flow of hot water flowing from top to bottom.

FIG. 24 shows a perspective view of a cartridge system 1200 having askirt 1202 with a sinusoidal configuration with length L, a width W1,and a gap between two adjacent waves being W2. The variables L, W1, andW2 may be adjusted to evenly saturate the beverage grind within thefilter mesh 1008. The cartridge system 1200 may have a lid

FIG. 25A shows an elongated plastic filter 1300 with pours 1302 sized toallow beverage to pass therethrough while containing the beverage grindtherewithin. The number of pours or density of pours may increase fromthe rim 1304 to the bottom 1306 to compensate for the increase inresistance to flow of liquid due the beverage grind formed in anelongated fashion due to the elongated filter 1300.

FIG. 25B shows a side view of the plastic filter 1300 with number ofpours 1302 varying along the length L from the rim 1304 to the bottom1306. The graph on the right shows that the density or number of pours1302 may vary linearly as shown by the graph 1308, in steps as shown bythe graph 1310, and non-linearly as shown by the graph 1312. Inaddition, for elongated filter 1300, the size of the beverage grindwithin the filter 1300 may vary along the length L as shown in graphs1308, 1310, and 1312 to compensate for the resistance to flow of liquiddeeper into the filter or as L increases. This may allow the hot liquidfrom the top needle to more evenly saturate the beverage grind in thefilter to brew more full body or even taste.

FIG. 26 shows a cross-sectional view an elongated cartridge system 1400adapted to fit inside the cup holder 718. The cartridge system 1400 mayinclude an elongated cup 1402 adapted to house an elongated filter 1404,and a lid 1406 to enclose the rim 1408 of the cup 1402. The cup 1402 maybe sized to fit inside the cup holder 718 such that the bottom 1410 ofthe cup 1402 may be pierced by the second needle 722 when the cartridgesystem 1400 is inserted into the cup holder 718. By way of background,traditional K-Cups® hold about 10 to 13 grams of coffee grind within thefilter. With the traditional K-Cups® being shorter than the elongatedcartridge system 1400, the coffee grind in the K-Cups® are held in ashort cylindrical fashion. This means that the hot water from the topneedle travels a shorter distance from the top to bottom of the coffeegrind in the K-Cups® compared to the cartridge system 1400. Putdifferently, the wash time or contact time between the hot water and thecoffee grind is relatively short because the travel distance is short.This may result in a less than full extraction of coffee flavor from thecoffee grind.

To increase the wash time between the hot water and the coffee grind,the filter 1404 may be elongated and configured to hold about 10 to 13grams of coffee grind in an elongated form from the rim 1412 to thebottom 1414 of the filter 1404. This may mean that the diameter D of thefilter 1404 may be smaller such that substantial gap 1416 may be formedbetween the filter 1404 and the cup 1402. With the increase wash time,more flavor may be extracted from the same coffee grind to brew a moreflavorful cup of beverage such as coffee. As discussed above inreference to FIG. 25B, the grind size may be varied to provide a moreeven saturation of the coffee grind within the filter 1404.

FIG. 26B shows a cross-sectional view of an elongated cartridge system1500 that is similar to the cartridge system 1400 expect that the rim1412 of the filter 1404 may be coupled to the lid 1406 such that the rim1412 of the filter 1404 is within the rim 1408 of the cup 1402.

FIG. 27 shows a cross-sectional view of a cartridge system 1600including a cup 1602 divided generally into a first chamber 1604 and asecond chamber 1606. The first chamber 1604 may be defined by the spacewithin the filter 1608 adapted to hold a first beverage grind 1610. Thesecond chamber 1606 may be the remaining space within the cup 1602. Thesecond chamber 1606 may hold a second beverage grind 1612. For example,the first beverage grind 1610 may be coffee grind, and the secondbeverage grind 1612 may be powder creamer and/or sweetener. Thecartridge system 1600 may include a lid 1614 adapted to seal around therim 1616 of the cup 1602. The lid 1614 may also have an inner flowdistributor 1618 adapted to expand within the first chamber 1604. Aportion of the rim 1619 of the filter 1608 may be sealed to the lid 1614such that there is a space 1621 between the rim 1619 of the filter 1608and the rim 1616 of the cup 1602.

The cartridge system 1600 may be adapted to work with a brewer systemthat orients the cartridge system 1600 in an angle 0 from a horizontalplane 1623 where direction arrow 1620 generally indicates the directionof gravity. The brewer system may provide a first needle 1622 adapted topierce the lid 1614 such that the tip 1624 of the first needle 1622expands the inner flow distributor 1618 and is guarded by the inner flowdistributor 1618 such that the first beverage grind 1610 does not clogthe first needle 1622. The brewer system may also provide a secondneedle 1626 that pierces the lid 1614 at the space 1621 to drain thebeverage within the cup 1602. As the first needle 1622 injects hot waterinto the filter 1608, the extracted beverage may permeate through thefilter 1608 and dissolve the second beverage grind 1612, such as powdercreamer, and the combination of beverage flavor may exit through thesecond needle 1626 as indicated by the direction arrows 1628.

FIG. 28A shows a perspective cross-sectional view of a cartridge system1700 including a cup 1702 housing a filter 1704. The rim 1706 of thefilter 1704 may be sealed around the inner edge 1708 of the cup locatedadjacent to the rim 1710 of the cup 1702. The cup 1702 may be sized tohave similar dimensions as K-Cup®. The filter 1704 may be configured tosubstantially fill the interior space of the cup 1702 such that thebottom 1712 of the filter 1704 may be juxtaposed to the basin 1714 ofthe cup 1702 to substantially maximize the interior space 1716 of thefilter 1704. This allows ease in which to pack the cup 1702 withbeverage grind and to pack as much as possible the beverage grindtherein. The basin 1714 of the cup 1702 may have one or more ribs 1718to provide a passageway 1720 between the ribs for the beveragepermeating out of the filter 1704 to flow therethrough. Note that it iswithin the scope of this invention to have a certain portion of thebottom 1712 of the filter 1704 be in contact with the basin 1714 of thecup. Alternatively, a gap may be formed between the bottom 1712 of thefilter 1704 and throughout the basin 1724 such no bottom portion 1712 ofthe filter 1704 is in contact with the basin 1714.

FIG. 28B shows a side cross-sectional view of the cartridge system 1700with the top needle 182 piercing through a top cover 1722, and thebottom needle 130 piercing through the basin 1714. The bottom 1712 ofthe filter 1704 may be juxtaposed to the basin 1714 such that when thebottom needle 130 piercing through the basin 1714, the bottom needle 130may push the bottom 1712 of the filter 1704 up, as indicated by a raisedportion 1724, without piercing through the raised portion of the filter1704 at a point of contact 1724 as shown in FIG. 28B.

The filter 1704 may be formed from a material that is substantiallyresistance to piercing by the bottom needle 130 while allowing thebeverage liquid to permeate therethrough during the brewing process. Thepressure within the cartridge may increase substantially during thebrewing process for the following reasons: (1) as heated water isinjected into the cartridge through the top needle, the beverage grindgenerally expands as the grind absorb heated water; (2) the heated waterfills the spaces within the cartridge, thus exerting outer pressure; and(3) the heat from the hot water increases the pressure within the cup.These factors apply pressure on the filter to expand during the brewingprocess such that a filter made of a weak material like the paper filterused in a K-cup® may tear when pressed against a sharp object like thebottom needle. This would result in the beverage grind being poured intoa mug, which is undesirable. As such, the filter according to thisinvention may be made from a cotton fabric material such as muslincotton, synthetic material such as nylon, or paper material engineeredto be resistant to piercing or tearing yet allowing the beverage liquidto permeate therethrough. Note that it is within the scope of theinvention to use a variety of filter material that is known to oneskilled in the art that is substantially resistant to piercing by thebottom needle 130 due to the pressure applied to the filter due to thebottom needle piercing through the cup and during the brewing process.With regard to the cartridge system 1700, the gap between the bottom1712 of the filter 1704 and the basin 1714 may be generally described asa space in which the bottom needle 130 may make contact with the bottom1712 of the filter 1704 after the bottom needle 130 has been fullyinserted into the bottom of the cup.

FIG. 29 shows a perspective cross-sectional view of a cartridge system1800 including a cup 1802 housing a filter 1804 where the filter 1804substantially fills the interior space 1806 of the cup. The bottom 1808of the filter 108 may be juxtaposed to the basin 1810 of the cup 1802with the filter material substantially resistant to piercing by thebottom needle in a manner similar to the cartridge system 1700 discussedabove in reference to FIG. 28. The cup 1802 and the filter 1804,however, may be longer along its longitudinal axis 1812 relative to thecup 1702 and the filter 1704.

While various embodiments of the invention have been described, it willbe apparent to those of ordinary skill in the art that many moreembodiments and implementations are possible within the scope of thisinvention. For instance, the powder creamer may be provided in a tabletform or in a pouch to easily insert into the cup. The cartridge systemmay not include a filter such that the cup holds a beverage grind thatmay be formulated to dissolve in such a way that the beverage does notclog the bottom needle. With the tall cup being able to hold greateramount of the beverage grind, a bigger cup of beverage may be brewedsuch as milk and soup.
